Abstract
Various embodiments are generally directed to techniques communicate in a cellular communication frequency range, detect a resonant signal in response to the communication in the cellular communication frequency range for cellular communication, the resonant signal to indicate presence of a contactless card. Embodiments also include enabling a near-field communication device to send a communication to the contactless card based on the detection of the resonant signal, the near-field communication device to communicate with the contactless card in a near-field communication frequency range.
